Question

I am trying to build a jQuery selector. This involves concatenating string and variables. However, for some reason, the resulting selector comes up invalid. I have attempted a number of options such as this:

$('[name="[name='$radioName + (row_id) + ']"][value="$result"]').attr('checked',true);

$radioName example is: ‘Nigeria[Osun][Okuku-;// the angle bracket is not closed as the row_id will be appended to it before the closing bracket is appended as shown above.

$result example is: ’67

row_id example is: 5

How may I build a valid descriptor with these requirements?

Thanks

Try:

$('[name="' + $radioName + row_id + ']' + '"][value="' + $result + '"]').attr('checked',true);

When I’m putting together concatenated expressions, using I write the static text with proper quotes first. Something like:

$('[name=""][value=""]').attr('checked',true);

Then I paste in '+ +' in each of the spots I want to add a variable. Like so:

$('[name="'+ +'"][value="'+ +'"]').attr('checked',true);

Then lastly, I add the variable:

$('[name="'+ $radioName + row_id + ']' + '"][value="'+ $result +'"]').attr('checked',true);
